The Fe-C alloy obtained by mechanical alloying and sintering

Purpose: The main aim of this work was to determine structure and properties massive Fe-C materials obtained by mechanical alloying and sintering. Design/methodology/approach: The results of experiments on the fabrication of powders materials and solid materials using pure iron and graphite powders are presented. The powders of the Fe-C alloys obtained by mechanical alloying method and after that the powders were sintering. The sintering process was conducted by using the impulse-plasma method. In this article the usability of mechanical alloying method and sintering to produce the massive materials were presented. Findings: The laboratory tests show that, by using the mechanical alloying method, one can produce powder of Fe-6.67% mass.C alloy with intentional chemical constitution and desirable structure. The structure of the materials is homogeneous and fine-grained and inside the materials didn’t find some impurities and undesirable phases. The sintering by using the impulse-plasma method makes the sinters with close to theoretical density with non-variable nanocrystaline microstructure possible. The hardness of the sinters was 1300 HV. Research limitations/implications: The mechanical alloying method is one of the techniques which enables to improve property of Fe-C alloys. It is possible by refinement of structure and modification of phases composition. Nanocrystaline size of grain is advisable to make it in correct technology of producing massive materials with nanocrystaline structure. All of the presented experiments in this article are conducted on a laboratory scale. At the present time, all over the world, the mechanical alloying and the sintering processes of nanocrystaline materials are only just in the laboratory scientific research. In the nearest future the producing of nanomaterials will take place not only in the laboratory and move to the industry. Originality/value: The nanomaterials have an unusual mechanical, physical and chemical properties.
